The lab will analyze stable isotopes oxygen-18 and deuterium in water samples collected in streams, lakes, wetlands, groundwater, and point sources. This data can identify primary flow sources under varying flow conditions (low to very high flows). Identifying sources can help identify pollutant sources or locate areas that are in need of protection. For example, you may want to protect an area that contributes cold groundwater to a coldwater fishery. Or it could link a water chemistry impairment to a specific source.
Cognizant to the needs of the stormwater community, a group that has engaged in stormwater research at the University of Minnesota (UMN) has developed a research program for the biennium that addresses pressing needs: a stormwater research roadmap and framework for priority needs, research required to improve stormwater pond maintenance, and information transfer related to these needs.
